This happens all too often. You can hide the problem by mixin up a little artist'soil paints and use a n old fashioned "spotting" brush like they used to use to retouch negatives. A couple of "values" should be enough to do the job. If you are not as steady, as I am not anymore, get a kid, preferable a teenager to help. They have better visual acuity and coordination. After you get the cracks filled in, leave it dry for a week, then, up to you what to do next. You can clean off the rest of the cabinet and spray the whole thing, or just touch up the finish with a little poly, again with a very small brush. Let dry for another week at least, and buff out any irregularites with a little pumice. All is reversable in case your expectations are not met. 999 other ways to do it.
